SIG Sauer is world famous for their high quality firearms, but now you can install one of their optics to your firearm as well. The SIG Sauer Tango6 Rifle Scope is a tactical series rifle scope designed for today's AR's and Bolt Action platforms. This scope is ideal for CQB, mid-range tactical engagements, 3-Gun Competition, and hunting. The Tango6 continues the tradition of using a proprietary HDX optical system that provides industry leading brightness and extreme optical clarity for any situation. All Tango6 units are built with LockDown Zero System turrets which feature a resettable zero, zero-stop, and lock-ability at any location. Another big feature of the Tango6 series is that they come in both first and second focal plane options so check carefully to ensure you order the one that is right for you..
